dwest576 Posted May 1, 2008 Share Posted May 1, 2008 Is it possible to use Dual PCIe ATI 2600 Pro's w/ 3 Monitors? I get all the kext's loaded and the cards show under System Profiler, I cannot get my 3rd monitor to show up and be used by the system. Is there a trick I am missing? Thanks, Dave Link to comment Share on other sites More sharing options...

crazyJAT Posted April 12, 2009 Share Posted April 12, 2009 The Mac Pro came with the option to install up to 4 HD2600xt cards at one point in time. I don't see why it wouldn't be possible. I also have 2 HD2600xt cards. One is a 256mb and one a 512mb. I have a P43 board with dual pci-x16 slots. I was unable to get all 4 (or even 3) of my monitors to work. Both cards were recognized in System Profiler but only one showed connected monitors. If anyone wants to move forward with this, we need to know a couple of things. 1. If it is a chipset issue, what is the chipset used in the Mac Pro that does support that? 2. Is it an issue with the cards themselves, drivers, natit, gfx strings? Doesn't seem so as System Profiler sees both cards, maybe the driver. 3. Has anyone had any ati configuration working with more than one ati video card? Would be great if we could get some people interested in this. I bought this board to play some windows games from time to time, but I am in web development and would love the ability to have a 3rd or 4th monitor.
